By use of ASTM C1202, this paper studied the influence of mineral admixtures on the chloride ions penetration resistance of the steam-cured concrete. The experimental results indicated that mineral admixtures improved the permeability properties of high-performance concretes, but at different rates depending on the binder type. FA required a relatively longer time to get its beneficial effect. For each 10%~40% replacement of OPC by FA in a concrete mix, the values of coulomb charge of steam-cured and standard curing concrete reduces by 8%~17% at180 days. When 30% weight of the OPC were replaced by FA and ground blast furnace slag(GBFS), the inclusion of 30% mineral admixtures provided a significant improvement to the chloride ions penetration resistance properties of steam-cured and standard curing concrete at 28 days and 180 days, especially for the combination of 10% FA and 20% GBFS (double adding).
